金剛石增強型硬質合金復合齒鉆頭在卵礫石層中的應用Applying those engineering techniques, at present, the following results are obtained : the ground temperatures on the top and at the bottom of an embankment made of crushed rock are all lower than those of common embankment, so the crushed rock embankment is of great advantage of decreasing embankment temperature, and becomes an effective and initiative engineering measure to protect permafrost ; the crushed rock embankment can actively adjust the temperature difference between south slop and north slop, and mitigate the asymmetry of ground temperature ; the deformation of the crushed rock embankment is less than that of common embankment
通過以上的施工技術，取得了相應的階段性成果：片石路基片石層頂面、底面與路基基底位置處地溫分別低於普通路基相同位置處地溫，片石路基有利於降低路基地溫，是一種有效的主動保護多年凍土工程措施；片石路基在調節路基陰陽坡地溫起到了積極的作用，減輕了路基地溫不對稱性的發生；對比片石路基和普通路基的路基變形量，片石路基的變形量相對較小。This is why a special tunnelling machine capable of excavating through both soft ground as well as hard rock was used. without this machine, the tunnelling would have to be done by cut - and - cover method, causing major traffic and environmental disruption. with this tbm, all these impacts can be avoided
